1st Look: Jaimie Alexander's SIF on AGENTS OF S.H.I.E.L.D.

Think Disney-Marvel is trying to sell some Thor: The Dark World Blu-rays?

TV Guide has the first looks at a couple of upcoming Thor-themed TV crossovers just in time for home video release of the hit Thor sequel. As previously reported, Jaimie Alexander will reprise her Thor and The Dark World role of Sif on the March 11 episode of Marvel's Agents of S.H.I.E.L.D. titled "Yes Men."

Thor's best friend (who's got a not-so-secret crush on him) stops by the ABC series to save Agent Coulson's team from Lorelei (Elena Satine), a Thor villain (the Enchantress's younger sister) created during Walter Simonson's legendary comic book run in the 1980's.

"We always have our radar up for ways to tie our series into the Marvel films and bringing in an Asgardian really cements that connection," executive producer Jed Whedon tells TV Guide. "Lady Sif comes here on a hunting mission — sent by Odin — to find her arch-enemy Lorelei and bring her back to Asgard. It throws our agents for a loop when they find themselves in a fight right alongside this powerful woman from Thor's world."

"Jaimie walked onto the set in full Lady Sif regalia just as she looks in the movies — from the huge, mile-high boots to the metal armor — and she towered over everyone," added executive producer Maurissa Tancharoen. "It was so striking and impressive, all we could do was stare. It was very cool!"

Additionally, TV Guide is also reporting Monday that the all-seeing, all-knowing Asgardian gatekeeper Heimdall will appear on the February 23 episode of Disney XD's Marvel's Hulk and the Agents of S.M.A.S.H.

Heimdall won't be voiced Idris Elba, however, so Marvel drafted NBA-Miami Heat star Chris Bosh (see what we did there?) to voice the role.

According to TV Guide the plot finds "Heimdall and Thor battling the mighty Hulks until the fate of the nine realms forces them to set aside their differences and join forces again über-villain Malekith and his wicked elves. "

Said new Marvel animation V.P. Stephen Wacker: "We were thrilled that Chris agreed to lend his voice to one of the biggest and bravest warriors of Asgard. We hope fans will enjoy this fun episode as Chris brings the heat to Team Green."
